Square Cartridge Heaters Customized Special Shape
Description:
Cartridge heater is a kind of heating elements made of MgO powder or MgO tube, ceramic cap, resistance wire(NiCr20/80). It is used to heat in plastic injection moulds, dies, platens .

Feature
For those applications where a drilled hole is not practical, GME offers square cartridge heaters. Unlike square cartridge heaters from other manufacturers, our square cartridge heaters are swaged, allowing them to be used in high temperature and high watt density applications.
Square heaters are ideal for milled slots in long platens where drilling a long hole would be too difficult. Square heaters are also much easier to remove from a slot after extended high temperature usage than removing a round heater from a drilled hole.
